Organic Impurities in Fine Aggregates for Concrete

ASTM C40

This test method is used in making a preliminary determination of the acceptability of fine aggregates with respect to the requirements of Specification C33/C33M that relate to organic impurities. The principal value of this test method is to furnish a warning that injurious amounts of organic impurities may be present. When a sample subjected to this test produces a color darker than the standard color, it is advisable to perform the test for the effect of organic impurities on the strength of mortar in accordance with Test Method C87/C87M.

WJE laboratories are accredited by AASHTO (R18) and ANAB (ISO/IEC 17025) to perform testing standard ASTM C40 for Organic Impurities in Fine Aggregates for Concrete. Contact us to learn more.
